Types of PCB, PCBA,Finished products Requiring Salt Spray Testing

1. PCBAs for High-Salt Environments

Automotive Electronics

• ECUs, ADAS sensors, and vehicle communication modules exposed to coastal climates or road de-icing agents require testing per ISO 9227 and IEC 60068-2-11 to validate solder joint and coating corrosion resistance.

Marine & Offshore Equipment

• Navigation systems and underwater communication devices undergo neutral salt spray (NSS) or cyclic salt spray tests to simulate prolonged marine exposure.

2. High-Reliability Industrial & Medical PCBAs

Medical Devices

• Surgical tools and patient monitors must comply with IEC 60601, requiring salt spray tests to ensure stability in humid or disinfectant-exposed environments.

• Focus on conformal coating integrity (e.g., epoxy or polyurethane) to prevent ionic migration.

Renewable Energy Systems

• Solar inverters and battery management PCBs deployed outdoors or in coastal areas need testing to assess relay contact and busbar corrosion risks.

3. Consumer & Communication Electronics

5G Infrastructure

• Base station antennas and RF modules in high-humidity coastal regions require copper-accelerated acetic acid salt spray (CASS) testing for gold/silver-plated contacts.

Outdoor Smart Devices

• IP-rated IoT products (e.g., security cameras, wearables) undergo testing to validate enclosure sealing and internal circuit protection.

4. PCBAs with Specialized Materials/Processes

Precision-Plated Components

• ENIG (Electroless Nickel Immersion Gold) or HASL (Hot Air Solder Leveling) finishes are tested for porosity and oxidation resistance.

Conformal-Coated Assemblies

• Coatings like acrylic or silicone are evaluated for blistering/delamination under salt spray conditions.

5. Certification-Driven Applications

Export to North America/Europe

• Compliance with ASTM B117 or IEC 60068-2-52 is mandatory for CE/UL certifications.

Military/Aerospace Electronics

• Follows MIL-STD-202 and GJB 150.11 to ensure functionality in extreme salt-laden environments.

Key Testing Parameters

Methods: NSS (pH 6.5–7.2), ASS (pH 3.1–3.3), or CASS (50°C with CuCl₂).

Advantages of Salt Spray Testing for PCB/PCBA

Accelerated Corrosion Validation

Salt spray testing simulates high-concentration salt mist environments (e.g., 5% NaCl solution) to rapidly identify corrosion risks in PCBs/PCAss that would take years to manifest in natural conditions8. For example:

48H/96H Testing: Quickly evaluates the corrosion resistance of coatings (e.g., gold/nickel plating) or conformal coatings, reducing product development cycles.

Extreme Condition Simulation: Supports 100+ hours of salt fog exposure or cyclic temperature-humidity tests, critical for automotive and medical electronics.

Standardized Quality Control

Compliant with global standards (ASTM B117, IEC 60068-2-11, ISO 9227), ensuring universally recognized results. Key features include:

Multi-Method Coverage: Neutral Salt Spray (NSS), Acetic Acid Salt Spray (ASS), and Copper-Accelerated Salt Spray (CASS) tests to meet diverse industry requirements67.

Quantitative Metrics: Corrosion area grading, weight loss analysis (≤7.5mg tolerance), and electrical performance validation for objective quality assessment3.

Design Optimization & Cost Efficiency

Material Selection: Compares corrosion resistance of coatings (e.g., Parylene nanocoating vs. traditional conformal coatings) to mitigate mass-production risks.

Failure Analysis: Identifies salt-induced defects like solder joint corrosion or coating delamination, guiding process improvements.

Compliance with Market Access & Regulations

Mandatory Certifications: Required for automotive electronics (ISO 16750), military hardware (MIL-STD-810F), and medical devices.

Regional Adaptability: Supports standards like GB/T 2423.17 (China) and ASTM (U.S.), facilitating global market entry.

Third-Party Laboratory Expertise

CNAS-accredited labs offer:

Precision Equipment: Temperature-controlled chambers (±2°C) and automated salt settlement monitoring.

Custom Solutions: Fast turnaround reports, specialized simulations (e.g., marine climates), and industry-specific protocols for automotive/medical electronics.

Key Applications:

Automotive ECUs and sensors exposed to coastal/road salt environments.

Medical PCBA reliability validation under sterilization and humidity.

PCB coatings (e.g., UV conformal coatings) for industrial equipment in corrosive settings.
